PLATFORM-SPRING CONNECTION.

' SPECIFICATION forming part of Letters Patent No. 274,277, dated March 20, 1883.

Application filed August 31, 1882.

. and useful Improvements in Spring-Connections for Half-Platform Wagons; and I do hereby declare that the following is a full,

clear, and exact description thereof.

My invention relates to what are known as half-platform spring-wagons; and it consists in adevice for connecting the middle bar to and F the middle bar.

the rear side sprin'gs,'as will be fully described hereinafter.

1n the drawings, Figure 1 is a perspective view of therear gear of a half-platform wagon,

and Figs. 2 and 3 are details.

A is the rear axle. B are the rear side springs; O, the rear cross-spring; D, a bolster carried by the rear cross-spring; E, the reach, When the body is in place its rear half is supported by the bolster D and middle bar, F. s

It hasbeen found, previous to my invention, very difficult to make a proper connection between the frontends of the springs B and the middle bar, F-that is, a connection that wofild permit the lengthening and shortening of the spring under pressure, and which would avoid that cramping action of the spring which is so liable to produce fracture; and hence my in- I vention consists in suspending a bracket,

B, from. each end of the middle bar, the middle bar fitting between ears b b, rising from the top of the bracket B, and at their lower pointsI provide each bracket with a pair of links, a a, which are pivoted thereto by bolts 0, and I pivot the upper ends of links a a, by bolts 0, to the frontends of the springs B B.

(No model.)

the links yielding to give free play to the front ends of the springs B, and therefore no amount ofjostling can cause the springs B to cramp or bind. While the ears I) b of my bracket project up to clamp the middle bar, its curved depending portion is curved so as to project under the middle bar in position to support its end of the spring directly beneath the middle bar.

What I'claim as my invention, and desire to secure by Letters Patent, is-- 1. In combination With the rearcross-spring and rear side springs, B B, and middle bar, F, the brackets B, having-ears b b rising therefrom to receive the middle bar, and curved depending portion projecting under said middle bar, at right angles thereto, and the pivoted links a, connected by bolts to the front ends of bolt 0, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand, on this 19th day of August, 1882, in the presence of two witnesses.
